UNITED STATES PATENT OFFICE.

JEAN SOHAFHAUS, OF NEW YORK, N. Y.

SWIMMING BEER=COOLER.

SPECIFICATION forming part of Letters Patent No. 280,405, dated July 3,1888.

Application filed April 10, 1883. (No model.)

To all whom it may concern.-

Be it known that I, JEAN SCHAFHAUS, a citi-. zen of the United States ofAmerica, residing at New York city, in the county of New York and Stateof New York, have invented certain new and useful Improvements inSwimming Beer-Coolers; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to that class of coolers used in cooling beer whilein fermenting-vats, the object of cooling the beer being the preservingof the saccharine matter therein and to retard the germination of thecarbonic-acid gas.

My cooler is expressly so constructed that the utmost cooling-surface isobtained.

I am aware that swimming coolers have heretofore been used; but none, tomy knowl edge, have the cooling-surface that I obtain by myconstruction.

The coolers heretofore used were constructed in the shape of an ordinarycylinder provided with a bottom, while mine is constructed of twoshells, and in such manner that a double cooling-surface is obtained.

I 11 the old style of swimming coolers it was necessary to weight thebottom, so as to pre vent the tipping of the cooler, while those constructed after my plan are prevented from tipping by the means of thewater-column which enters the space (1..

Figure 1 represents a vertical section of a vat with my improvedswimming beer-cooler in position. Figs. 2. 3, and 4 are modifications ofthe swimming beer-cooler.

In the drawings, A represents the fermenting-vat; B, the cooler; 12, theouter shell; I)", the inner shell; I), the ring or rim, which latter,however, may be dispensed with, it not being a vital part of theinvention.

Of course these coolers may be made of any suitable material or form,and suitable means may be provided for lifting the coolers whennecessary. 7

When it is desired to counterweight the coolers for the purpose ofpreventing any possibility of tipping the same, it is only necessary tofasten the weights in the drawings at X.

The manner heretofore adopted in practice of employing the swimmerswithout lifting them out of the fermentingvat for the purpose of fillingthem again with ice was to simply use a hose as a siphon.

By means of the coolers as constructed according to my plan I have beenenabled to cool the contents of a vat in .one-half of the timeheretofore required. This is of great consequence, since the longer thebeer, after it has reached the fermenting state in its process ofmanufacture, remains in a temperature of, say, 8 or 9 Reaumur, thegreater the loss of saccharine matter, which is very detrimental. Thegreat object sought to be brought about by the use of coolers is theimmediate (if it were possible) reduction of the temperature of thebeer. The vessel or cooler may be filled with ice or cold water, asdesired.

In Figs. 2, 3, and 4. I have shown modifications of form of my cooler.

I prefer the construction of a cooler as shown in Fig. 1, since it isobvious that the coolingsurface is much greater than that shown in the Vv modification.

'When desirable, I construct the coolers with a ring or pipe, 0,soldered on the outside upper portion, as shown in Fig. 3.

' I am aware that swimming beer-coolers have been used and patented; butthey differ in construction from mine, and I disclaim them; but

What'I claim as new, and desire to secure by Letters Patent, is

1. The swimming beer-cooler B. having the shell I) and b", said shellsbeing united at their lower ends, as shown, and having the rim If, incombination with the balanceweights X and chains, arranged substantiallyas and for the purpose set forth.

2. The swimming beer-cooler B herein de scribed, consisting of theshells b and I)", united at their lower ends, as shown, in combinationwith the balance weights X and chains, and the ring 0, arranged as andfor the purpose set forth. v

3. The swimming beer cooler B, having shells b and b and a conoidalspace, a, in combination with the balance-weights X and chains, arrangedsubstantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
